The purpose of this article is to analyse undocumented immigrants' right to access to health care and their access in practice. Undocumented immigrants have a right to equal access to health care. Access to more than emergency health care in Denmark is dependent on immigration status. Medical doctors' duty to treat does not apply to non-emergency health needs, and the options existing in this situation remain ambiguous. However, in practice, undocumented immigrants in Denmark are able to receive more than emergency health care through unofficial networks of health care providers.
